Just as your phone functions as an extension of yourself — allowing you to do and know things you couldn't otherwise — phone accessories allow phones to perform tasks they simply can't on their own. Yes, even the all-powerful iPhone 5s.

Whether it's adding an exoskeleton to keep your brand-new gadget safe from alcohol-induced mishaps or a wireless speaker to bolster its relatively puny sound capacity, the right accessory can add a ton of functionality and value to an already super-functional and very valuable piece of hardware. If you're looking for a top-of-the-line gadget that will turn your 5s into a finely tuned workout-optimizing machine or simply something to help keep all your adapter cable needs sorted out, this list offers the discerning iPhone 5s user a plethora of picks to simplify and improve the phone-user relationship.

(Of course, if you decided to stick with your iPhone 5 and wait until the next update, rest assured that, since the two phones are the same size and shape and use the same mobile operating system, these accessories will do the trick for your phone, too.)

Cases

While some people are afraid to tarnish the natural beauty of their iPhones by covering them with a clunky case, this case from Spigen is a nifty solution, mimicking the existing iPhone back using diamond-cut aluminum. The cases come in champagne, silver and space gray versions — like the iPhone 5s — as well as red/black.

OtterBox Commuter Series Case%displayPrice% at %seller% If your first concern is safety, though, OtterBox is the company for you. Their Commuter case is a protective cocoon for your iPhone, with a thin plastic sheet protecting your screen and a two-layer protective backing that envelops the phone in silicone and polycarbonate to offer a soft cushion and a hard shell against all the little bumps and scrapes your phone encounters.

If you want your phone to stay stylish while staying scratch-free, consider Apple’s own leather cases. While a little pricey for such a simple case, they’ll offer you the satisfaction of touching real leather every time you handle your phone.

Grove's got a host of sleek wooden cases to give your phone an old-school feel, but their new WoodPrint case will have your iPhone 5s covered in a unique design, allowing you to upload up to three photos that they'll imprint onto your case.

If it's not your phone you want to protect, but what's on the screen, consider the BodyGuardz Privacy ScreenGuardz. Offering you protection from spying eyes while allowing you to view your Twitter feed, this plastic film will also protect your screen from scratches.

Tethering

The Apple TV adds a whole new dimension of power to your iPhone by allowing you to stream games and video content directly to your television, turning that four-inch screen into a giant panorama of Candy Crush and allowing you to relive your favorite concerts through the video you took.

This handy wristband is something of a revolution in fitness tracking. Paired with your iPhone via a free app, the UP allows you to track your sleep habits, your exercise and the food you eat. Then it’ll make recommendations for you so you can bett

er tackle getting — and staying — in shape. It’s designed to be worn all day and all night, and has a 10-day battery life to accommodate that.

If you want to focus more on the active part of your life, or if the UP’s price is just a tad steep for you, the Fitbit Flex offers a lot of the same functionality, with a free app so you can track your stats on your iPhone. On top of that, the Flex’s silent wake function will get you going in the morning without waking up whoever’s sleeping next to you — pretty handy.

It'll set your wallet back a bit, but the QX100 is a DSLR-quality camera lens that attaches to your phone and syncs with it wirelessly via a free app. If you're a photographer not satisfied with the new iPhone camera, this means the end of having to carry around both your phone and a full, bulky camera.
